EDWARD J. RELPI-I, OF CHICAGO, ILLINOIS, ASSIGNOR TO TAYLOR SIG-NAL COMPANY, OF BUFFALO, NEW YORK, A CORPORATION OF NEV YORK.

FRAILWAYHSIGNAL SPECIFICATION forming part of Letters Patent No. 759,310, dated May 10, 1904..

Application filed August 13, 1903.

To @ZZ whom t may concern:

Be it known that I, EDWARD J. RELPH, a subject of the King of Great Britain, residing at Chicago, Illinois, have invented certain new and useful Improvements in Railway-Signals,

of which the following is a full, clear, and eX- act description.

My invention relates to railway-signals, and more especially to the improved construction IO of the signal-blade or semaphore proper.

To this end my invention consists of the mechanism and construction shown in the accompanying' drawings, in which-- Figure l is an elevation of my invention,

I5 showing the signal at dangen Fig. 2 is a similar view showing the signal at safety.

It will be seen that in the drawings I have shown my invention as applied to a dwarf signal, and while it is peculiarly adaptable to 2O such use it is also capable of use in connection with an ordinary signal.

l is a post, preferably of metal, which carries the signal.

2 is a case containing the mechanism for operating thc signal.

3 is an ordinary signal-lantern, which is carried by the bracket 4, mounted upon the standard or post l.

5 is a shaft, (shown in dotted outline in the drawings,) which is journaled in a cap to the post l and to which is transmitted motion in rotation over a small arc of a circle from the mechanism contained within the casing 2. Any desirable form of mechanism may be cm- 3 5 ployed to cause this motion.

6 is a disk, which is rigidly mounted upon a plate 7, which is shown in dotted outline. This plate 7 is rigidly mounted in turn upon a shaft 5. The disk is shown as eccentrically mounted, although the mounting may be concentric with the disk, the purpose of the eccentric mounting being to economize space. The disk 6 carries a band of color S across its face, the color of which may be made to suit the use of the signal desired, the color red being indicated in the drawings. The rest of Serial No. 169,340. (No model.)

the disk 6 is white enamel, so as to give sharp contrast between it and the color-band. Rotation of the disk 6 upon the shaft 5 will shift this band from the danger position (shown in Fig. l) to the safety position. (Shown in Fig. 2.) The disk 6 also carries glass disks 9 and 10, which are so mounted upon it that when the signal is in one position one disk will be concentric with the lamp-lens and when the signal is in the other position the other disk will be in a similar position with reference to the lamp-lens.

It will thus be seen that the signal, particularly in the case of the dwarf signal, results in much economy of space, does away with flexible signals, is simple in construction, and easy of operation. It presents a bold and striking outline, the color-band showing up clearly against the white background,and prevents confusion with surrounding external parts of the signal.

Having thus described my invention and its method of operation, what I claim isl. In combination withasignal-post and operating mechanism, a disk, a shaft, said disk being' mounted in rotation with said shaft, means for rotating said shaft over an arc of a circle, a color-band extending across the face of said disk in contrasting color with the re- 7 5 maining surface of said disk, a signal-lantern carried on said post and two lenses mounted on said disk, and so positioned that when the disk is in one position one lons registers with the lantern-lens, and when the disk is in the 8O opposite position, the other lens registers with the lantern-lens, substantially as and for the purposes set forth.

2. A railway-signal comprising a disk capable of rotation over an arc of a circle, a color- 8 5 band extending across the face of the disk, and the remaining portion of the face of the disk being of contrasting color, and means for rotating said disk, substantially as and for the purposes set forth. 9o

3. A signal disk, comprising, a circular plate and means for rotating the same, a colorband across its face und contrasting with the In witness whereof I have hereunto set my color of the face of the signal to constitute :t hand, in the presence of two witnesses, this day-signal, and lenses mounted upon said disk 30th day of July, 1903.
